Simple Toon Shader New

From GameStudio Wiki

This version of the simple toon shader works with DirectX9 and only requires VS 1.0. :) Your entities skin should be made of solid colors(no gradients or photorealistic stuff) to get the cartoonish look. ;)

You will need one picture file:

If you scroll down to this line:

vertexShaderConstant[16]=0.3; // outline thickness

You may change the thickness of the black line by changing the 0.3 to a higher value or a lower value for thinner lines.

bmap bmp_toonlookup=<toonlookup.tga>;

material mtl_toon
{
	skin1=bmp_toonlookup;
	effect =
	"
matrix matWorldViewProj;
matrix matWorld;vector vecSunDir;
texture entSkin1;texture mtlSkin1;
technique t0{
pass p0 // shade it
{

VertexShaderConstant[4] = <matWorld>;
VertexShaderConstant[7] = <vecSunDir>;

Have fun! ;)
